OLFA KH-1/L-5 18mm Ratcheting Lock Utility Knife with Locking Holster

The OLFA KH-1/L-5 18mm Ratcheting Lock Utility Knife with Locking Holster is built for professionals who need a heavy-duty cutting tool that stays secure and ready on the job. This combo pack pairs the OLFA L-5 18mm ratchet-lock utility knife with a locking holster designed for fast access, reliable retention, and everyday belt carry. With an oversized belt loop, quick-release lever, and lanyard hole, the holster supports jobsite movement while helping keep the knife close at hand. For warehouse crews, contractors, painters, maintenance teams, and industrial users, this setup provides a practical way to carry a utility knife safely without slowing down daily work.

The knife itself is designed for demanding cutting tasks and repeated use. Its glass-fiber reinforced body gives it lightweight strength, while the wraparound anti-slip grip helps users maintain control when cutting heavier materials. The ratchet-lock blade actuator allows one-touch blade extension and lets users set the blade at the depth needed for the task. A stainless-steel support channel improves blade stability, and the tool-free blade change keeps downtime low. Preloaded with an LBB 18mm Ultra-Sharp Black Snap-Off Blade, the knife delivers aggressive cutting performance with eight blade segments ready for use. The built-in multi-purpose metal pick adds extra value for scraping caulk, opening can lids, or unscrewing outlet plates without risking damage to the blade tip.
